  • Title: [The question of indication for surgery in renovascular hypertension].
    Author: Esch I, Sacher W.
    Journal: Acta Med Austriaca; 1975; 2(1):18-26. PubMed ID: 1227227.
    Abstract:
    11 of 22 patients with angiographical identified unilateral stenosis of renal artery underwent a reconstruction of vessels. 11 patients were treated according to conservative methods. To achieve a prognosis, we compared pressure gradient and methods based on determination of plasma renin activity (PRA) including the difference of concentration of PRA in both renal veins as well the relationship between the concentration in the renal veins and peripheral blood and the suppression of the renin secretion in the undamaged kidney. In cases when all prognostic criteria were in positive accordance, operation was successful (7 cases). When there was no accordance, we noticed a correlation between pressure gradient and surgical success in 3 cases and predicaments based on PRA and success in 2 cases. Pressure gradient is pointed out as important parameter, 3 of non operated patients showed a progression of this disease.
